They can take cold nights, say mid-thirties F, if no frost, but don’t like summer heat. Most of mine are in clay pots, and I bring them inside in the summer if it’s going to be in the 80’s.
In the heat the plants will put everything into the flowers and "forget" to grow a replacement tuber. If you don't have side shoots, rather cut the flower. The cut flowers can last long enough to mature seed---if you feel inclined to breed it. The seed germinate very easily on wet sphagnum moss.
